Principal Graph and Structure Learning Based on Reversed Graph Embedding.
IEEE Transactions on Pattern Analysis and Machine Intelligence(2017)
摘要
Many scientific datasets are of high dimension, and the analysis usually requires retaining the most important structures of data. Principal curve is a widely used approach for this purpose. However, many existing methods work only for data with structures that are mathematically formulated by curves, which is quite restrictive for real applications. A few methods can overcome the above problem, b...
